The only difference between the old and new versions of the RCI2950 is the new CPU board. They require slightly different modifications. Old Version The old version of this radio can be expanded from 26 Mhz to 32 Mhz. Although the use of the 30 -32 Mhz range may need realignment. First find the PC board with the jumpers on (behind the front panel).Then find 'J2',there is a jumper on pins P3 and P4.If this is jumper is removed you will get coverage from 26 Mhz to 29.7 Mhz. If this jumper is then place on P1 and P2 coverage will be from 26 Mhz to 32 Mhz(re tuning may be needed to operate in 30-32 Mhz range). The CPU now needs to be reset by pressing the button located below 'J2' New Version As the CPU board has changed the modification is different. On the CPU board there is only one jumper with two positions available. In one position it covers 28 Mhz to 30 Mhz, In the other it covers 26 Mhz to 30 Mhz. But if you jump all three pins together you'll get 26 Mhz to 30 Mhz.
